How can I calculate respiration rate from a respiration signal based on specific onsets?

Dear Matlab experts,
I have a respiration data and I wish to find a way to calculate the respiration rate in specific epochs that I can manually specify.
Is there a way to do that? or any known toolbox?
Thank you very much in advance, Gil

Hi matlab experts,
I need to extract 3 types of signals (ecg, Respiration, PPG) and need to estimate beat to beat heart rate, breath to breath respiratory rate, pulse to pulse pulse rate from those signals. Someone please help me. Thanks in advance.

You should be able to just do that with a frequency-domain analysis by either computing the DFT (via FFT), or using a nonparametric PSD estimator from the Signal Processing Toolbox, periodogram(), or pwelch()

Hi. anyone know the equation to calculate respiration rate?
I try to use this coding but it seem like for the heart beat.
dataset = xlsread('rrest-syn192_data.xlsx','Sheet1','A1:B30000')
s = dataset(:,1)
%y = dataset(:,2)
data = [s];
N1 = length(s)
t=0:1/500 : N1/500-1/500
plot(t,s)
title('Plot of signal')
xlabel('Time')
ylabel('Sample(s)')
[pks,locs,w,p] = findpeaks(data)
a=size(pks)
peak_count = (a/2)
Duration_s = (N1/500)
Duration_m = (Duration_s/60)
total_rate_per_minute = (peak_count/Duration_m)

So far we need to used Digital filtering and wavelet decomposition method to extract the respiration rate?
